When aluminum is allowed to stand in air or is heated in air, a thin oxide film is produced on the metal. If aluminum is made the anode in a suitable electrolyte and a current applied, a coating is obtained which is similar to that produced in air, but may be effected much quicker. This film is thicker, harder, more resistant to corrosion and abrasion, and more adhesive than the natural oxide. The film is porous and makes an excellent adsorptive for dyes and pigments.
